BACKGROUND OF THE INVENTION 1. Technical Field

The present invention relates generally to an optical system, and more particularly to a compact optical image capturing system for an electronic device.

2. Description of Related Art

In recent years, with the rise of portable electronic devices having camera functionalities, the demand for an optical image capturing system is raised gradually. The image sensing device of the ordinary photographing camera is commonly selected from charge coupled device (CCD) or complementary metal-oxide semiconductor sensor (CMOS Sensor). In addition, as advanced semiconductor manufacturing technology enables the minimization of the pixel size of the image sensing device, the development of the optical image capturing system towards the field of high pixels. Therefore, the requirement for high imaging quality is rapidly raised.

The conventional optical system of the portable electronic device usually has five or six lenses. However, the optical system is asked to take pictures in a dark environment, in other words, the optical system is asked to have a large aperture. The conventional optical system provides high optical performance as required.

It is an important issue to increase the quantity of light entering the lens. In addition, the modern lens is also asked to have several characters, including high image quality.

BRIEF SUMMARY OF THE INVENTION

The aspect of embodiment of the present disclosure directs to an optical image capturing system and an optical image capturing lens which use combination of refractive powers, convex and concave surfaces of seven-piece optical lenses (the convex or concave surface in the disclosure denotes the geometrical shape of an image-side surface or an object-side surface of each lens on an optical axis) to increase the quantity of incoming light of the optical image capturing system, and apply the design of an engaging component adapted to locate the lenses therein to improve imaging quality for image formation, so as to be applied to minimized electronic products.

The term and its definition to the lens parameter in the embodiment of the present are shown as below for further reference.

The lens parameter related to a length or a height in the lens:

A maximum height for image formation of the optical image capturing system is denoted by HOI. A height of the optical image capturing system is denoted by HOS. A distance from the object-side surface of the first lens to the image-side surface of the seventh lens is denoted by InTL. A distance from the first lens to the second lens is denoted by IN12 (instance). A central thickness of the first lens of the optical image capturing system on the optical axis is denoted by TP1 (instance).

The lens parameter related to a material in the lens:

An Abbe number of the first lens in the optical image capturing system is denoted by NA1 (instance). A refractive index of the first lens is denoted by Nd1 (instance).

The lens parameter related to a view angle in the lens:

A view angle is denoted by AF. Half of the view angle is denoted by HAF. A major light angle is denoted by MRA.

The lens parameter related to exit/entrance pupil in the lens:

An entrance pupil diameter of the optical image capturing system is denoted by HEP. An exit pupil of the optical image capturing system refers to the image of the aperture stop imaged in the imaging space after passing through the lens behind the aperture stop, and the exit pupil diameter is denoted by HXP. For any surface of any lens, a maximum effective half diameter (EHD) is a perpendicular distance between an optical axis and a crossing point on the surface where the incident light with a maximum viewing angle of the system passing the very edge of the entrance pupil. For example, the maximum effective half diameter of the object-side surface of the first lens is denoted by EHD11, the maximum effective half diameter of the image-side surface of the first lens is denoted by EHD12, the maximum effective half diameter of the object-side surface of the second lens is denoted by EHD21, the maximum effective half diameter of the image-side surface of the second lens is denoted by EHD22, and so on.

The parameters related to an assembling mechanism between the lenses:

The object-side surface of each lens in the optical image capturing system, if required, could be provided with an object-side bearing surface (denoted as BSO), and the image-side surface thereof, if required, could be also provided with an image-side bearing surface (denoted as BSI). For each lens, the object-side bearing surface and the image-side bearing surface thereof, if required, could be engaged with a contact surface of the adjacent lens in front or in back of said lens to form a stack structure, wherein a contour length of said contact surface on a radial direction is denoted as BSL. Said stack structure, if required, could be designed as “one-engaging”, which means there are only two lenses engaged with each other. For example, say the image-side surface of the first lens has a first image-side bearing surface, and the object-side surface of the second lens has a second object-side bearing surface, wherein the second object-side bearing surface and the first image-side bearing surface contact each other, and are engaged together. Such engaging structure is called “one-engaging”. Or, the stack structure could be designed as “two-engaging”. For example, in addition to the one-engaging mentioned above, the image-side surface of the second lens has a second image-side bearing surface, and the object-side surface of the third lens has a third object-side bearing surface, wherein the third object-side bearing surface and the second image-side bearing surface contact each other, and are engaged together. Such engaging structure is called “two-engaging”.

Or, the stack structure could be designed as “three-engaging” or “all-engaging”. Take an optical image capturing system having seven lenses as an example. In addition to the aforementioned “two-engaging”, the image-side surface of the third lens has a third image-side bearing surface, and the object-side surface of the fourth lens has a fourth object-side bearing surface, wherein the fourth object-side bearing surface and the third image-side bearing surface contact each other, and are engaged together; the image-side surface of the fourth lens has a fourth image-side bearing surface, and the object-side surface of the fifth lens has a fifth object-side bearing surface, wherein the fifth object-side bearing surface and the fourth image-side bearing surface contact each other, and are engaged together; the image-side surface of the fifth lens has a fifth image-side bearing surface, and the object-side surface of the sixth lens has a sixth object-side bearing surface, wherein the sixth object-side bearing surface and the fifth image-side bearing surface contact each other, and are engaged together; the image-side surface of the sixth lens has a sixth image-side bearing surface, and the object-side surface of the seventh lens has a seventh object-side bearing surface, wherein the seventh object-side bearing surface and the sixth image-side bearing surface contact each other, and are engaged together.

Take the aforementioned “all-engaging” structure of the optical image capturing system having seven lenses as an example, an extension line of each image-side bearing surface among the first image-side bearing surface to the seventh image-side bearing surface could be defined as extending toward the object side or the image plane to meet different requirements, which intersects the optical axis at an included angle IAG, wherein the included angle between the optical axis and each extension line of each image-side bearing surface is respectively denoted as IAG1, IAG2, IAG3, IAG4, IAG5, IAG6, and IAG7 in sequence. Similarly, an extension line of each object-side bearing surface among the first object-side bearing surface to the seventh object-side bearing surface could be defined as extending toward the object side or the image plane to meet different requirements, which intersects the optical axis at an included angle OAG, wherein the included angle between the optical axis and each extension line of each object-side bearing surface is respectively denoted as OAG1, OAG2, OAG3, OAG4, OAG5, OAG6, and OAG7 in sequence.

The size of aforementioned included angles IAGs and OAGs has to be adjusted by human. Generally speaking, the greater the IAGs and OAGs are, the optical image capturing system would have more room for miniature, but the engagement between the lenses might be less tight. On the contrary, the smaller the IAGs and OAGs are, the optical image capturing system would have less room for miniature, but the engagement between the lenses could be tighter.

While being assembled inside a structural positioning member (e.g., a lens barrel), the specific assembling of the lenses might become tilted if an inner wall of the structural positioning member does not have sufficient precision, which would affect the imaging quality. The aforementioned stack structure could prevent this problem. In addition, when it comes to miniaturize the optical image capturing system or the pixels of a matching image sensor, the precision of the assembling and the bearing between the lenses would significantly affect the final imaging quality. The aforementioned stack structure could ensure that the actual performance provided by the assembling and the bearing between the lenses would be close to what is expected.

The lens parameter related to an arc length of the shape of a surface and a surface profile:

For any surface of any lens, a profile curve length of the maximum effective half diameter is, by definition, measured from a start point where the optical axis of the belonging optical image capturing system passes through the surface of the lens, along a surface profile of the lens, and finally to an end point of the maximum effective half diameter thereof. In other words, the curve length between the aforementioned start and end points is the profile curve length of the maximum effective half diameter, which is denoted by ARS. For example, the profile curve length of the maximum effective half diameter of the object-side surface of the first lens is denoted by ARS11, the profile curve length of the maximum effective half diameter of the image-side surface of the first lens is denoted by ARS12, the profile curve length of the maximum effective half diameter of the object-side surface of the second lens is denoted by ARS21, the profile curve length of the maximum effective half diameter of the image-side surface of the second lens is denoted by ARS22, and so on.

In other words, the curve length between the aforementioned stat point and the coordinate point is the profile curve length of a half of the entrance pupil diameter (HEP), and is denoted by ARE.

An offset of the coma aberration is denoted by DFC.

Transverse aberration on an edge of an aperture is denoted by STA, which stands for STOP transverse aberration, and is used to evaluate the performance of one specific optical image capturing system. The transverse aberration of light in any field of view can be calculated with a tangential fan or a sagittal fan. More specifically, the transverse aberration caused when the longest operation wavelength (e.g., 650 nm) and the shortest operation wavelength (e.g., 470 nm) pass through the edge of the aperture can be used as the reference for evaluating performance. The coordinate directions of the aforementioned tangential fan can be further divided into a positive direction (upper light) and a negative direction (lower light). The longest operation wavelength which passes through the edge of the aperture has an imaging position on the image plane in a particular field of view, and the reference wavelength of the mail light (e.g., 555 nm) has another imaging position on the image plane in the same field of view. The transverse aberration caused when the longest operation wavelength passes through the edge of the aperture is defined as a distance between these two imaging positions. Similarly, the shortest operation wavelength which passes through the edge of the aperture has an imaging position on the image plane in a particular field of view, and the transverse aberration caused when the shortest operation wavelength passes through the edge of the aperture is defined as a distance between the imaging position of the shortest operation wavelength and the imaging position of the reference wavelength.

Furthermore, for a stricter evaluation, the performance cannot be considered excellent unless the transverse aberrations of the shortest and the longest operation wavelength which pass through the edge of the aperture and image on the image plane in 0.7 field of view are both less than 80 μm.

For any surface of any lens, the profile curve length within the effective half diameter affects the ability of the surface to correct aberration and differences between optical paths of light in different fields of view. With longer profile curve length, the ability to correct aberration is better. However, the difficulty of manufacturing increases as well. Therefore, the profile curve length within the effective half diameter of any surface of any lens has to be controlled. The ratio between the profile curve length (ARS) within the effective half diameter of one surface and the thickness (TP) of the lens, which the surface belonged to, on the optical axis (i.e., ARS/TP) has to be particularly controlled.

For any surface of other lenses in the optical image capturing system, the ratio between the profile curve length of the maximum effective half diameter thereof and the thickness of the lens which the surface belonged to is denoted in the same manner.

For any surface of any lens, the profile curve length within a half of the entrance pupil diameter (HEP) affects the ability of the surface to correct aberration and differences between optical paths of light in different fields of view. With longer profile curve length, the ability to correct aberration is better. However, the difficulty of manufacturing increases as well. Therefore, the profile curve length within a half of the entrance pupil diameter (REP) of any surface of any lens has to be controlled. The ratio between the profile curve length (ARE) within a half of the entrance pupil diameter (REP) of one surface and the thickness (TP) of the lens, which the surface belonged to, on the optical axis (i.e., ARE/TP) has to be particularly controlled.

For any surface of other lenses in the optical image capturing system, the ratio between the profile curve length of a half of the entrance pupil diameter (REP) thereof and the thickness of the lens which the surface belonged to is denoted in the same manner.

In an embodiment, a height of the optical image capturing system (HOS) can be reduced if |f1|>|f7|.

In an embodiment, when |f2|+|f3|+|f4|+|f5|+|f6| and |f1|+|f7| of the lenses satisfy the aforementioned conditions, at least one lens among the second to the sixth lenses could have weak positive refractive power or weak negative refractive power. Herein the weak refractive power means the absolute value of the focal length of one specific lens is greater than 10. When at least one lens among the second to the sixth lenses has weak positive refractive power, it may share the positive refractive power of the first lens, and on the contrary, when at least one lens among the second to the sixth lenses has weak negative refractive power, it may fine turn and correct the aberration of the system.

In an embodiment, the seventh lens could have negative refractive power, and an image-side surface thereof is concave, it may reduce back focal length and size. Besides, the seventh lens can have at least an inflection point on at least a surface thereof, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

In an embodiment, the lenses of high Abbe number and the lenses of low Abbe number are arranged in an interlaced arrangement that could be helpful for correction of aberration of the system.

An equation of aspheric surface is

z=ch ²/[1+[1(k+1)c ² h ²]^(0.5) ]+A4h ⁴ +A6h ⁶ +A8h ⁸ +A10h ¹⁰ +A12h ¹² +A14h ¹⁴ +A16 h ¹⁶ +A18h ¹⁸ +A20h ²⁰+ . . .  (1)

In the optical image capturing system, the lenses could be made of plastic or glass. The plastic lenses may reduce the weight and lower the cost of the system, and the glass lenses may control the thermal effect and enlarge the space for arrangement of the refractive power of the system. In addition, the opposite surfaces (object-side surface and image-side surface) of the first to the seventh lenses could be aspheric that can obtain more control parameters to reduce aberration. The number of aspheric glass lenses could be less than the conventional spherical glass lenses, which is helpful for reduction of the height of the system.

When the lens has a convex surface, which means that the surface is convex around a position, through which the optical axis passes, and when the lens has a concave surface, which means that the surface is concave around a position, through which the optical axis passes.

The optical image capturing system of the present invention could be applied in a dynamic focusing optical system. It is superior in the correction of aberration and high imaging quality so that it could be allied in lots of fields.

The optical image capturing system of the present invention could further include a driving module to meet different demands, wherein the driving module can be coupled with the lenses to move the lenses. The driving module can be a voice coil motor (VCM), which is used to move the lens for focusing, or can be an optical image stabilization (OIS) component, which is used to lower the possibility of having the problem of image blurring which is caused by subtle movements of the lens while shooting.

To meet different requirements, at least one lens among the first lens to the seventh lens of the optical image capturing system of the present invention can be a light filter, which filters out light of wavelength shorter than 500 nm. Such effect can be achieved by coating on at least one surface of the lens, or by using materials capable of filtering out short waves to make the lens.

To meet different requirements, the image plane of the optical image capturing system in the present invention can be either flat or curved. If the image plane is curved (e.g., a sphere with a radius of curvature), the incidence angle required for focusing light on the image plane can be decreased, which is not only helpful to shorten the length of the system (TTL), but also helpful to increase the relative illuminance.

The object-side surface of each lens in the optical image capturing system provided in the present invention, if required, could be provided with an object-side bearing surface (denoted as BSO), and the image-side surface thereof, if required, could be also provided with an image-side bearing surface (denoted as BSI). For each lens, the object-side bearing surface and the image-side bearing surface thereof, if required, could be engaged with a contact surface of the adjacent lens in front or in back of said lens to form a stack structure, wherein a contour length of said contact surface on a radial direction is denoted as BSL, which satisfies 0.01 mm≦BSL≦1 mm, and preferably satisfies 0.05 mm≦BSL≦0.5 mm. In a best mode, it can further required to satisfy 0.08 mm≦BSL≦0.2 mm.

In the optical image capturing system of the present invention, said stack structure, if required, could be designed as “one-engaging”, which means there are only two lenses engaged with each other. For example, say the image-side surface of the first lens has a first image-side bearing surface, and the object-side surface of the second lens has a second object-side bearing surface, wherein the second object-side bearing surface and the first image-side bearing surface contact each other, and are engaged together. Such engaging structure is called “one-engaging”. Or, the stack structure could be designed as “two-engaging”. For example, in addition to the one-engaging mentioned above, the image-side surface of the second lens has a second image-side bearing surface, and the object-side surface of the third lens has a third object-side bearing surface, wherein the third object-side bearing surface and the second image-side bearing surface contact each other, and are engaged together. Such engaging structure is called “two-engaging”.

Or, the stack structure could be designed as “three-engaging” or “all-engaging”. Take an optical image capturing system having seven lenses as an example. In addition to the aforementioned “two-engaging”, the image-side surface of the third lens has a third image-side bearing surface, and the object-side surface of the fourth lens has a fourth object-side bearing surface, wherein the fourth object-side bearing surface and the third image-side bearing surface contact each other, and are engaged together; the image-side surface of the fourth lens has a fourth image-side bearing surface, and the object-side surface of the fifth lens has a fifth object-side bearing surface, wherein the fifth object-side bearing surface and the fourth image-side bearing surface contact each other, and are engaged together; the image-side surface of the fifth lens has a fifth image-side bearing surface, and the object-side surface of the sixth lens has a sixth object-side bearing surface, wherein the sixth object-side bearing surface and the fifth image-side bearing surface contact each other, and are engaged together; the image-side surface of the sixth lens has a sixth image-side bearing surface, and the object-side surface of the seventh lens has a seventh object-side bearing surface, wherein the seventh object-side bearing surface and the sixth image-side bearing surface contact each other, and are engaged together.

An extension line of each image-side bearing surface among the first image-side bearing surface to the seventh image-side bearing surface could be defined as extending toward the object side or the image plane to meet different requirements, which intersects the optical axis at an included angle IAG, wherein the included angle between the optical axis and each extension line of each image-side bearing surface is respectively denoted as IAG1, IAG2, IAG3, IAG4, IAG5, IAG6, and IAG7 in sequence, which satisfies 0 deg<IAG≦90 deg. The size of the aforementioned IAG1 to IAG7 could be designed to meet the actual requirement of an optical image capturing system, and it is preferred to satisfy 0 deg<IAG≦45 deg. In a best mode, it can be further required to satisfy 0 deg<IAG≦30 deg, and IAG1=IAG2=IAG3=IAG4=IAG5=IAG6=IAG7, which means all IAGs are approximately equal. In a specific embodiment, the condition can be set as 0 deg<IAG≦30 deg. In yet another specific embodiment, there can be a further condition that requires one of IAG1 and IAG7 is the smallest one.

Take the aforementioned “all-engaging” structure of the optical image capturing system having seven lenses as an example, an extension line of each object-side bearing surface among the first object-side bearing surface to the seventh object-side bearing surface could be defined as extending toward the object side or the image plane to meet different requirements, which intersects the optical axis at an included angle OAG, wherein the included angle between the optical axis and each extension line of each object-side bearing surface is respectively denoted as OAG1, OAG2, OAG3, OAG4, OAG5, OAG6, and OAG7 in sequence, which satisfies 0 deg<OAG≦90 deg. The size of the aforementioned OAG1 to OAG7 could be designed to meet the actual requirement of an optical image capturing system, and it is preferred to satisfy 0 deg<OAG≦45 deg. In a best mode, it can be further required to satisfy 0 deg<OAG≦30 deg, and OAG1=OAG2=OAG3=OAG4=OAG5=OAG6=OAG7, which means all OAGs are approximately equal. In a specific embodiment, the condition can be set as 0 deg<OAG≦30 deg. In yet another specific embodiment, there can be a further condition that requires one of OAG1 and OAG7 is the smallest one.

The detail parameters of the first embodiment are listed in Table 1, in which the unit of the radius of curvature, thickness, and focal length are millimeter, and surface 0-10 indicates the surfaces of all elements in the system in sequence from the object side to the image side. Table 2 is the list of coefficients of the aspheric surfaces, in which A1-A20 indicate the coefficients of aspheric surfaces from the first order to the twentieth order of each aspheric surface. The following embodiments have the similar diagrams and tables, which are the same as those of the first embodiment, so we do not describe it again.

Second Embodiment

As shown in FIG. 2A and FIG. 2B, an optical image capturing system 20 of the second embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 210, a second lens 220, a third lens 230, an aperture 200, a fourth lens 240, a fifth lens 250, a sixth lens 260, a seven lens 270, an infrared rays filter 280, an image plane 290, and an image sensor 292. FIG. 2C is a transverse aberration diagram at 0.7 field of view of the second embodiment of the present application. In the second embodiment, all image-side bearing surfaces and all object-side bearing surfaces are designed as extending toward the object side, and each of them intersects the optical axis at an included angle (not shown).

The first lens 210 has negative refractive power and is made of glass. An object-side surface 212 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 214 thereof, which faces the image side, is a concave aspheric surface.

The second lens 220 has negative refractive power and is made of glass. An object-side surface 222 thereof, which faces the object side, is a concave aspheric surface, and an image-side surface 224 thereof, which faces the image side, is a concave aspheric surface.

The third lens 230 has positive refractive power and is made of plastic. An object-side surface 232, which faces the object side, is a convex aspheric surface, and an image-side surface 234, which faces the image side, is a convex aspheric surface.

The fourth lens 240 has positive refractive power and is made of glass. An object-side surface 242, which faces the object side, is a convex surface, and an image-side surface 244, which faces the image side, is a convex surface.

The fifth lens 250 has negative refractive power and is made of plastic. An object-side surface 252, which faces the object side, is a concave aspheric surface, and an image-side surface 254, which faces the image side, is a concave aspheric surface. The image-side surface 254 has an inflection point.

The sixth lens 260 has positive refractive power and is made of plastic. An object-side surface 262, which faces the object side, is a convex aspheric surface, and an image-side surface 264, which faces the image side, is a convex aspheric surface. The image-side surface 264 has an inflection point. Whereby, incident angle of each field of view for the sixth lens can be effectively adjusted to improve aberration.

The seventh lens 270 has positive refractive power and is made of plastic. An object-side surface 272, which faces the object side, is a convex surface, and an image-side surface 274, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, the image-side surface 274 has two inflection points, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 280 is made of glass and between the seventh lens 270 and the image plane 290. The infrared rays filter 280 gives no contribution to the focal length of the system.

The parameters of the lenses of the second embodiment are listed in Table 3 and Table 4.

Third Embodiment

As shown in FIG. 3A and FIG. 3B, an optical image capturing system of the third embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 310, an aperture 300, a second lens 320, a third lens 330, a fourth lens 340, a fifth lens 350, a sixth lens 360, a seventh lens 370, an infrared rays filter 380, an image plane 390, and an image sensor 392. FIG. 3C is a transverse aberration diagram at 0.7 field of view of the third embodiment of the present application. In the third embodiment, all image-side bearing surfaces and all object-side bearing surfaces are designed as extending toward the object side, and each of them intersects the optical axis at an included angle (not shown).

The first lens 310 has positive refractive power and is made of plastic. An object-side surface 312 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 314 thereof, which faces the image side, is a concave aspheric surface. The image-side surface 314 has two inflection points.

The second lens 320 has negative refractive power and is made of plastic. An object-side surface 322 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 324 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 322 and the image-side surface 324 both have an inflection point.

The third lens 330 has positive refractive power and is made of plastic. An object-side surface 332 thereof, which faces the object side, is a concave aspheric surface, and an image-side surface 334 thereof, which faces the image side, is a convex aspheric surface. The object-side surface 332 and the image-side surface 334 both have an inflection point.

The fourth lens 340 has positive refractive power and is made of plastic. An object-side surface 342, which faces the object side, is a concave aspheric surface, and an image-side surface 344, which faces the image side, is a convex aspheric surface. The object-side surface 342 has four inflection points, and the image-side surface 344 has an inflection point.

The fifth lens 350 has negative refractive power and is made of plastic. An object-side surface 352, which faces the object side, is a concave aspheric surface, and an image-side surface 354, which faces the image side, is a convex aspheric surface. The image-side surface 354 has an inflection point.

The sixth lens 360 has positive refractive power and is made of plastic. An object-side surface 362, which faces the object side, is a convex surface, and an image-side surface 364, which faces the image side, is a convex surface. The object-side surface 362 has three inflection points, and the image-side surface 364 has four inflection points. Whereby, incident angle of each field of view for the sixth lens can be effectively adjusted to improve aberration.

The seventh lens 370 has negative refractive power and is made of plastic. An object-side surface 372, which faces the object side, is a concave surface, and an image-side surface 374, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, the object-side surface 372 has two inflection points, and the image-side surface 374 has an inflection point, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 380 is made of glass and between the seventh lens 370 and the image plane 390. The infrared rays filter 390 gives no contribution to the focal length of the system.

The optical image capturing system 10 of the first embodiment further satisfies ΣPP=57.1785 mm; and f1/ΣPP=0.2408, where ΣPP is a sum of the focal lengths fp of each lens with positive refractive power. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system 10 of the first embodiment further satisfies ΣNP=−53.3826 mm; and f2/ΣNP=0.1153, where ΣNP is a sum of the focal lengths fp of each lens with negative refractive power. It is helpful to share the negative refractive power of the sixth lens to other negative lenses.

The parameters of the lenses of the third embodiment are listed in Table 5 and Table 6.

Fourth Embodiment

As shown in FIG. 4A and FIG. 4B, an optical image capturing system 40 of the fourth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 410, an aperture 400, a second lens 420, a third lens 430, a fourth lens 440, a fifth lens 450, a sixth lens 460, a seventh lens 470, an infrared rays filter 480, an image plane 490, and an image sensor 492. FIG. 4C is a transverse aberration diagram at 0.7 field of view of the fourth embodiment of the present application. In the fourth embodiment, all image-side bearing surfaces and all object-side bearing surfaces are designed as extending toward the object side, and each of them intersects the optical axis at an included angle (not shown).

The first lens 410 has positive refractive power and is made of plastic. An object-side surface 412 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 414 thereof, which faces the image side, is a concave aspheric surface. The image-side surface 414 has two inflection points.

The second lens 420 has negative refractive power and is made of plastic. An object-side surface 422 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 424 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 422 and the image-side surface 424 both have an inflection point.

The third lens 430 has positive refractive power and is made of plastic. An object-side surface 432 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 434 thereof, which faces the image side, is a convex aspheric surface. The object-side surface 432 has two inflection points, and the image-side surface 434 has an inflection point.

The fourth lens 440 has positive refractive power and is made of plastic. An object-side surface 442, which faces the object side, is a concave aspheric surface, and an image-side surface 444, which faces the image side, is a convex aspheric surface. The image-side surface 444 has an inflection point.

The fifth lens 450 has negative refractive power and is made of plastic. An object-side surface 452, which faces the object side, is a concave aspheric surface, and an image-side surface 454, which faces the image side, is a convex aspheric surface. The image-side surface 454 has two inflection points.

The sixth lens 460 has positive refractive power and is made of plastic. An object-side surface 462, which faces the object side, is a convex surface, and an image-side surface 464, which faces the image side, is a convex surface. The object-side surface 462 and the image-side surface 464 both have two inflection points. Whereby, incident angle of each field of view for the sixth lens can be effectively adjusted to improve aberration.

The seventh lens 470 has negative refractive power and is made of plastic. An object-side surface 472, which faces the object side, is a concave surface, and an image-side surface 474, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, the object-side surface 472 has an inflection point, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 480 is made of glass and between the seventh lens 470 and the image plane 490. The infrared rays filter 480 gives no contribution to the focal length of the system.

The optical image capturing system 10 of the first embodiment further satisfies ΣPP=56.0883 mm; and f1/ΣPP=0.2233, where ΣPP is a sum of the focal lengths fp of each lens with positive refractive power. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system 10 of the first embodiment further satisfies ΣNP=−87.3758 mm; and f2/ΣNP=0.0585, where ΣNP is a sum of the focal lengths fp of each lens with negative refractive power. It is helpful to share the negative refractive power of the sixth lens to other negative lenses.

The parameters of the lenses of the fourth embodiment are listed in Table 7 and Table 8.

Fifth Embodiment

As shown in FIG. 5A and FIG. 5B, an optical image capturing system of the fifth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 510, a second lens 520, a third lens 530, an aperture 500, a fourth lens 540, a fifth lens 550, a sixth lens 560, a seventh lens 570, an infrared rays filter 580, an image plane 590, and an image sensor 592. FIG. 5C is a transverse aberration diagram at 0.7 field of view of the fifth embodiment of the present application. In the fifth embodiment, all image-side bearing surfaces and all object-side bearing surfaces are designed as extending toward the object side, and each of them intersects the optical axis at an included angle (not shown).

The first lens 510 has positive refractive power and is made of plastic. An object-side surface 512, which faces the object side, is a convex aspheric surface, and an image-side surface 514, which faces the image side, is a concave aspheric surface.

The second lens 520 has negative refractive power and is made of plastic. An object-side surface 522 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 524 thereof, which faces the image side, is a concave aspheric surface. The image-side surface 254 has an inflection point.

The third lens 530 has positive refractive power and is made of plastic. An object-side surface 532, which faces the object side, is a convex aspheric surface, and an image-side surface 534, which faces the image side, is a concave aspheric surface.

The fourth lens 540 has positive refractive power and is made of plastic. An object-side surface 542, which faces the object side, is a concave surface, and an image-side surface 544, which faces the image side, is a convex surface.

The fifth lens 550 has positive refractive power and is made of plastic. An object-side surface 552, which faces the object side, is a convex aspheric surface, and an image-side surface 554, which faces the image side, is a convex aspheric surface. The object-side surface 552 has an inflection point.

The sixth lens 560 can have positive refractive power and is made of plastic. An object-side surface 562, which faces the object side, is a convex surface, and an image-side surface 564, which faces the image side, is a convex surface. The object-side surface 562 has two inflection points, and the image-side surface 564 has an inflection point. Whereby, incident angle of each field of view for the sixth lens 560 can be effectively adjusted to improve aberration.

The seventh lens 570 has negative refractive power and is made of plastic. An object-side surface 572, which faces the object side, is a concave surface, and an image-side surface 574, which faces the image side, is a convex surface. It may help to shorten the back focal length to keep small in size. In addition, the object-side surface 572 and the image-side surface 574 both have an inflection point, which may help to shorten the back focal length to keep small in size. In addition, it could effectively suppress the incidence angle of light in the off-axis view field, and correct the off-axis view field aberration.

The infrared rays filter 580 is made of glass and between the seventh lens 570 and the image plane 590. The infrared rays filter 580 gives no contribution to the focal length of the system.

The optical image capturing system 10 of the first embodiment further satisfies ΣPP=178.9037 mm; and f1/ΣPP=0.4233, where ΣPP is a sum of the focal lengths fp of each lens with positive refractive power. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system 10 of the first embodiment further satisfies ΣNP=−41.0270 mm; and f7/ΣNP=0.7332, where ΣNP is a sum of the focal lengths fp of each lens with negative refractive power. It is helpful to share the positive refractive power of one single lens to other negative lenses.

The parameters of the lenses of the fifth embodiment are listed in Table 9 and Table 10.

Sixth Embodiment

As shown in FIG. 6A and FIG. 6B, an optical image capturing system of the sixth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 610, an aperture 600, a second lens 620, a third lens 630, a fourth lens 640, a fifth lens 650, a seventh lens 660, a seventh lens 670, an infrared rays filter 680, an image plane 690, and an image sensor 692. FIG. 6C is a transverse aberration diagram at 0.7 field of view of the sixth embodiment of the present application. In the sixth embodiment, all image-side bearing surfaces and all object-side bearing surfaces are designed as extending toward the object side, and each of them intersects the optical axis at an included angle (not shown).

The first lens 610 has positive refractive power and is made of plastic. An object-side surface 612, which faces the object side, is a convex aspheric surface, and an image-side surface 614, which faces the image side, is a convex aspheric surface. The object-side surface 612 has an inflection point.

The second lens 620 has negative refractive power and is made of plastic. An object-side surface 622 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 624 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 622 and the image-side surface 624 both have an inflection point.

The third lens 630 has positive refractive power and is made of plastic. An object-side surface 632, which faces the object side, is a convex aspheric surface, and an image-side surface 634, which faces the image side, is a convex aspheric surface. The object-side surface 612 has an inflection point.

The fourth lens 640 has positive refractive power and is made of plastic. An object-side surface 642, which faces the object side, is a convex aspheric surface, and an image-side surface 644, which faces the image side, is a convex aspheric surface. The object-side surface 642 has two inflection points.

The fifth lens 650 has negative refractive power and is made of plastic. An object-side surface 652, which faces the object side, is a concave aspheric surface, and an image-side surface 654, which faces the image side, is a convex aspheric surface. The object-side surface 652 and the image-side surface both have two inflection points.

The sixth lens 660 can have positive refractive power and is made of plastic. An object-side surface 662, which faces the object side, is a convex surface, and an image-side surface 664, which faces the image side, is a convex surface. The object-side surface 662 has two inflection points, and the image-side surface 664 has three inflection points. Whereby, incident angle of each field of view for the sixth lens 660 can be effectively adjusted to improve aberration.

The seventh lens 670 has negative refractive power and is made of plastic. An object-side surface 672, which faces the object side, is a convex surface, and an image-side surface 674, which faces the image side, is a concave surface. The object-side surface 672 and the image-side surface 674 both have an inflection point. It may help to shorten the back focal length to keep small in size. In addition, it may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 680 is made of glass and between the seventh lens 670 and the image plane 690. The infrared rays filter 680 gives no contribution to the focal length of the system.

The optical image capturing system 10 of the first embodiment further satisfies ΣPP=62.7420 mm; and f1/ΣPP=0.2381, where ΣPP is a sum of the focal lengths fp of each lens with positive refractive power. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system 10 of the first embodiment further satisfies ΣNP=−88.6984 mm; and f7/ΣNP=0.0806, where ΣNP is a sum of the focal lengths fp of each lens with negative refractive power. It is helpful to share the positive refractive power of one single lens to other negative lenses.

The parameters of the lenses of the sixth embodiment are listed in Table 11 and Table 12.
